Donphan are light-gray elephant-like Pokémon. There is a thick, black band of hide that runs down the length of Donphan's back and extends to the trunk, resembling a car tire. Donphan have four short legs with three claws with each leg having a black band around them. They also sport a pair of white tusks, and elongated ears held stiffly to Donphan's sides.
It has the ability to curl up into a ball and violently roll around like a wheel. Once it starts its rampage it will be almost unstoppable. These rolling tackles are strong enough to knock down a house. Its hide is also very tough. Regular attacks won't leave a scratch on it.
Donphan travel in a herd that is led by a single Donphan. The larger the tusks, the higher its rank in the herd will be. They are also prone to going on violent rampages by curling into a ball and rolling almost nonstop. During their breeding season, male Donphan compete for mates by rolling as well to show how tough they are. This rolling is known as the Love Dance. Donphan are also known to have a keen sense of smell, at least in the sense of being able to detect amberite, and will upraise their trunks into the air to smell for it.
